As shown in fig. 2, the gantry crane is mounted on the supporting portion 200 of the gantry crane support, and the supporting portion 200 is in a low-level state at this time, that is, the bottom end of the gantry crane is in a state of being close to the track at this time, and in this state, the height of the gantry crane is low, so that the height limitation of the railway can be easily avoided. When the gantry crane is transported to the guide beam, an operator needs to operate the supporting part 200 to lift up on the connecting part 300 and fix the supporting part 200 through the limiting part 400, and at the moment, the height of the bottom end of the gantry crane accords with the height capable of being smoothly lowered onto the guide beam, so that the gantry crane can be conveniently and rapidly lowered. In the lifting process of the supporting portion 200, the supporting portion 200 can be lifted by an external force, or the structure itself can be provided with a lifting system, for example, the connecting portion 300 comprises a hydraulic device arranged at the top end of the base portion 100 and a hydraulic output shaft rotatably connected with the supporting portion 200, and a circular groove for inserting the hydraulic output shaft is correspondingly formed in the bottom end center of the supporting portion 200.

In this embodiment, the limiting portion 400 includes a pair of limiting blocks 403, a first limiting end 401 of which is hinged to the supporting portion 200, a second limiting end 402 of which is in pin connection with the supporting portion 200, and a pin connection end of the limiting block 403 is used as a main stress portion limited by the connecting portion 300, and the limiting blocks 403 are provided with a pair of limiting blocks, so that stress between the limiting blocks and the connecting portion 300 in the limiting process is more uniform, loss of the structure is reduced, and space occupied by the limiting blocks 403 in the process of avoiding the connecting portion 300 can be effectively reduced. The telescopic pin shaft in the transverse pin hole of the limiting block 403 comprises end shafts with polarities at two ends and an electromagnet at the middle part, and an operator can control the on-off of the current inside the electromagnet to change a magnetic field, so that the end shafts are attracted or repelled, and the end shafts can be conveniently inserted into or withdrawn from the transverse pin holes of the first connecting block 203. The retractable pin is not limited to the above embodiment, but may be a rod-like structure having a retractable capability such as an electric retractable rod.
As shown in fig. 2, a thickening layer 404 is provided at one end of the stopper 403 near the through hole. In this embodiment, the end of the limiting block 403 close to the through hole is the end stressed by the connecting portion 300, so that a thickening layer 404 may be provided, the stress intensity of the limiting block 403 may be effectively increased by providing the thickening layer 404, the stability of limiting the connecting portion 300 may be ensured, and as a more optimized scheme, the thickening layer 404 may be integrally formed with the limiting block 403.
The thickening layer 404 is provided on the side of the stopper 403 remote from the connecting portion 300. In this embodiment, the gravity center of the limiting block 403 can be changed in the process of avoiding the connection portion 300 by further limiting the position of the thickened layer 404, that is, when the second limiting end 402 is separated from the supporting portion 200, the limiting block 403 is far away from the connection portion 300 under the action of the thickened layer 404, so that the movement of the limiting block 403 is limited, and the phase-changing function of fixing the limiting block 403 is achieved, so that equipment abrasion caused by contact between the limiting block 403 and the connection portion 300 is avoided.
As shown in fig. 3, the supporting portion 200 includes a supporting block 201, through holes, a limiting block 403, and a first connecting block 203 all disposed on the supporting block 201, the supporting portion 200 further includes supporting arms 202 hinged on two sides of the supporting block 201 and capable of turning upwards, a second connecting block 204 is disposed on the supporting arms 202, and in a state that the supporting arms 202 turn upwards, a telescopic pin shaft is connected with a pin hole pin of the second connecting block 204. In this embodiment, the supporting arm 202 is provided, when the gantry crane support is moved to one end of the carrying Liang Zhuanlie for stacking, the supporting arm 202 can be turned upwards, so that the horizontal length of the gantry crane support is effectively reduced, the space in the horizontal direction can be effectively saved, and more placing space and operation space are provided for other devices. In order to ensure that the support arm 202 can be placed vertically stably, after the support arm 202 is turned upwards, the telescopic pin shaft inside the limiting block 403 is controlled to be connected with the pin hole formed in the second connecting block 204, so that the limiting block 403 and the support arm 202 are mutually matched and limited, the limiting block 403 can be prevented from being contacted with the connecting part 300, the support arm 202 is prevented from being turned downwards, the telescopic pin shaft is further utilized, and the utilization rate of the telescopic pin shaft is maximized. For better structure, the limiting block 403 may be in a split door form, and the supporting arms 202 are also in a split door form and are respectively arranged on the extension lines of the limiting block 403.
As shown in fig. 2 and 5, the connection part 300 has a cylindrical structure and is matched with the shape of the through hole. In the present embodiment, the shape of the connecting portion 300 and the through hole is defined such that the supporting portion 200 can rotate around the connecting portion 300, which has the advantage that the supporting portion 200 can be rotated when the gantry crane is transported, so that the length direction of the gantry crane is consistent with the railway traveling direction, thereby effectively avoiding the problem that the gantry crane exceeds the railway width limit. When the gantry crane is transported to the guide beam, the support 200 is rotated.
As shown in fig. 2, the top end of the connection part 300 is provided with a flat cylindrical spacer 301, and the diameter of the spacer 301 is smaller than that of the connection part 300.

The traveling part 500 includes traveling wheels 501 for traveling on a rail, and anti-rollover wheels 502 provided outside the rail for preventing the base part 100 from rolling over. In this embodiment, the travelling wheel 501 is mainly responsible for the movement of the structure, and the anti-rollover wheel 502 can avoid the adverse conditions of rollover of the structure.
It should be noted that, as shown in fig. 4 and 6, the lifting of the supporting portion 200 may be achieved by a gantry crane having a lifting function. As shown in fig. 4, the gantry crane comprises a load-bearing main beam 701 provided with a hoisting system, four first supporting legs 702 are uniformly and symmetrically fixed at the lower end of the load-bearing main beam 701, a guide channel is arranged at the bottom end of the first supporting legs 702, second supporting legs 705 with travelling gear trains 704 are movably inserted in the guide channel, reinforcing ribs 706 are connected between the lower ends of the second supporting legs 705 in the width direction of the gantry crane, and the reinforcing ribs 706 are connected with the load-bearing main beam 701 right above the load-bearing main beam 701 through jacking cylinders 707. The second supporting leg 705 can be driven to lift in the guiding channel of the corresponding first supporting leg 702 by the pushing and pulling force of the jacking cylinder 707, so as to realize the lifting motion of the gantry crane, and the inner sides of the first supporting legs 702 are also provided with clamping blocks 703 for being matched with the supporting parts 200, and in the supporting process of the supporting parts 200 on the gantry crane, the supporting parts 200 are propped against the bottom ends of the clamping blocks 703.
When the gantry crane needs to be sent to the end 603 of the guide beam arm, the supporting portion 200 and the clamping block 703 of the gantry crane can be fixed, the fixing can be performed by adopting a conventional technology such as a bolt or a fastener, then the lifting cylinder 707 is controlled to stretch, at this time, the clamping block 703 of the gantry crane rises to drive the supporting portion 200 to rise along the connecting portion 300, and then the limiting block 403 and the first connecting block 203 are fixed through a telescopic pin shaft. The lift cylinder 707 is then retracted, and the lift cylinder 707 then lifts the second leg 705 via the stiffener 706.
The bottom end of the gantry crane is equal to or slightly higher than the end 603 of the guide beam arm, if the bottom end of the gantry crane is just equal to the end 603 of the guide beam arm, the gantry crane can be directly lowered onto the end 603 of the guide beam arm, and the situation that the gantry crane is unstably lowered due to the height difference is avoided; if the travelling wheel system 704 is slightly higher, the lift cylinder 707 needs to be controlled to extend, and the second leg 705 can extend and contact the nose portion 603 of the girder arm, so that the girder arm can be smoothly lowered. At this time, the gantry crane is smoothly lowered onto the end 603 of the guide beam arm, and then the gantry crane can smoothly enter the middle 601 of the guide beam arm.
